DETAILED DESCRIPTION

[0020] The following is a detailed description of a Roots blower transmission component disassembly device of the utility model with reference to the accompanying drawings of the specification.

[0021] See also Figure 1-6 The utility model provides a Roots blower transmission component disassembly device, which structure includes a disassembly tool 3 and a driving mechanism, wherein the disassembly tool includes a mother tool 31 and a child tool 33, and the driving mechanism includes a hydraulic cylinder 5 and a disassembly rod 4, one end of the disassembly rod 4 is connected to the mother tool 31, and the free end of the telescopic rod of the hydraulic cylinder 5 abuts against the transmission component. The driving mechanism includes a hydraulic cylinder 5, a hydraulic cylinder support 6 and a disassembly rod 4, the cylinder body of the hydraulic cylinder 5 is connected to the hydraulic cylinder support 6, and the free end of the telescopic rod of the hydraulic cylinder 5 abuts against the axis of the transmission component, and two disassembly rods 4 are provided, one end of the disassembly rod 4 is fastened and connected to the hydraulic cylinder support 6 by a nut, and the other end of the disassembly rod 4 passes through the mother tool 31 and is fastened and connected by a nut.

[0022] The disassembly tool 3 includes a mother tool 31, a sub-tool 33 and a fixing bolt 35. The mother tool 31 includes two symmetrically arranged ear seat structures. The upper and lower ends of the two ear seat structures are respectively fastened and connected by fixing bolts 35. The inner side of the mother tool 31 is respectively provided with a sub-tool 33. The sub-tool is fixed to the mother tool by a connecting bolt 32. The sub-tool can be replaced by the connecting bolt according to the different outer diameters of the transmission parts to be disassembled, and the applicability is strong. The middle parts of the two ear seat structures of the mother tool 31 are respectively provided with connecting holes 34 that cooperate with the disassembly pull rod 4. By setting the mother tool, the sub-tool and the fixing bolts, it can adapt to the disassembly of various types of transmission parts, and the versatility is strong.

[0023] like Figure 1 As shown, the transmission member is a pulley 2, and the pulley 2 is arranged at one end of the blower 1. When the pulley 2 is disassembled, the pulley is fixed by disassembling the main tool 31, the sub-tool 33 and the fixing bolt 35 of the tool 3, and the hydraulic cylinder 5 is actuated. Since the free end of the telescopic rod abuts against the axis of the pulley 2, the telescopic rod is extended to give the transmission member an inward push force. At this time, the removal of the pull rod 4 will obtain an outward reaction force to remove the entire pulley, thereby realizing that the device uses the outer contour of the transmission member to fix and disassemble from the outside, which is easy to operate and saves time and effort.

[0024] like Figure 6As shown, the hydraulic cylinder support 6 includes a base 61, a first support plate 62, a hydraulic cylinder support plate 64 and a second support plate 65. The first support plate 62 is provided on the right side of the top of the base 61. The first support plate 62 is provided with two long holes 63 for adjusting the position of the disassembly rod 4. The second support plate 65 is provided on the left side of the top of the base. The second support plate 65 is provided with two long holes 63 corresponding to the first support plate 62. A groove for engaging with the hydraulic cylinder 5 is provided in the middle of the upper part of the second support plate 65. The hydraulic cylinder support plate 64 is provided between the first support plate 62 and the second support plate 65. A groove 66 is provided in the middle of the hydraulic cylinder support plate 64. The disassembly rod 4 passes through the corresponding long hole 63 and then matches with the connecting hole 34 on the female tooling, and then is fastened by a nut. Since the long holes are provided on the first support plate 62 and the second support plate 65, the disassembly rod 4 slides along the long hole to adjust the distance between the two disassembly rods, thereby adapting to female tooling of different models and meeting the disassembly of transmission parts of different sizes. The cylinder body of the hydraulic cylinder 5 is clamped in the grooves in the middle of the hydraulic cylinder support plate 64 and the second support plate 65, which plays a role in supporting and fixing the hydraulic cylinder.

The length of the spacer sleeve can adjust the diameter of the mother tool, adapt to the fixing of transmission parts of different sizes, and has strong applicability.

[0026] The transmission component disassembly device of the utility model can realize the rapid disassembly of transmission components with different outer profiles and outer diameters by means of the disassembly tooling in cooperation with the driving mechanism, which is convenient to operate and only requires one set of tooling.
